From: the milky way galaxy, third planet from the Sun.

Hobbies: crunching work units at SETI@home ain't I?
Thoughts about SETI and SETI@home
1) Yes, extraterrestrial life exists.
No, we will not discover it (not in my life time).
So, there are no benefits or dangers of such discovery.
2) We can attempt to send a beacon, but since we're located in
the middle of freaking nowhere, no aliens will bother with
our solar system. Check to see what's the next closest,
nearest possible/probable galaxy near ours...and you know
what I'm talking about (pretty depressing).
Beacon message: S.O.S. get us out of this freaking galaxy.
